Four years ago, I had no idea how big our duo would become. Not only have we gone on tours, and performed on radio and television shows, but over 500 million copies of each of our albums have been sold. On a different note, journal, Sheppard and I are so thankful that God has given us the gift of music, the amazing oppor-tunity of making music, and the many wonderful things that have come of and with it. We will forever be grateful.
